Oudenodon is an extinct genus of dicynodont. It was common throughout southern Africa during the Late Permian. Several species of Oudenodon are known.^[2] Both O. bainii, the type species, and O. grandis are known from South Africa (Cistecephalus Assemblage Zone and Endothiodon Assemblage Zone).^[3]^[4] Specimens of O. luangwensis have been found from Zambia.^[5] One species, O. sakamenensis from the Lower Sakamena Formation is the only Permian therapsid yet described from Madagascar.^[6] It is the type genus of the family Oudenodontidae, which includes members such as Tropidostoma.

Oudenodon is concluded on the basis of its δ¹⁸O_p values to have been an ectothermic animal.^[7]
